a fault, electrical shock, or fire may occur.
Do not use the disk array unit in an area where inflammable gas and/or
combustible substance are placed. If so, fire or an explosion may occur.
Do not concentrate power cords to just a few AC outlets. If so, fire may occur.
Do not set heavy materials on any power cord. If so, the coating of the power
cord may be broken, fire may occur, and/or you may be electrically shocked.
Do not install the disk array unit in an area of high humidity or dust. Remove any
dust adhering to AC outlets and the plugs of power cords. If dust accumulates on
an AC outlet and/or plug, fire may occur.
Do not connect the plug of a power cord to an AC outlet with wet hands. If so, you
may be electrically shocked.
The disk array unit can accept the power in the range of 100 - 240 VAC (50/60
Hz). Using power of a different voltage may cause electric shock, smoke, and/or
fire to occur.
The controller of the disk array unit contains a lithium battery. Do not remove the
lithium battery. The lithium battery may explode when it is brought close to fire or
when immersed in water. Dispose of the controller according to local ordinances.
Contact your local government for details.
If the disk array unit does not operate normally due to the life of the lithium
batteries, contact your service representative. Do not disassemble the controller,
or replace or charge the battery by yourself.
CAUTION
Do not install the disk array unit and the host systems in an unstable environment.
If so, the equipment may fall causing injury to you and/or the array.
Do not install the disk array unit and the power cords in any area with direct
sunshine or near any apparatus generating heat such as a heater. If so, a fault may
occur. Further, the protective coating of the power cords may be damaged causing
fire or electric shock to occur.
Insert the plug of a power cord to an AC outlet securely. Any power cord shall be
routed with sufficient margin to avoid excess force from being given to the plugs of
the power cord or the power cord itself. If a power cord is removed from the AC
outlet during operation, data may be lost and/or a fault may occur.
To prevent electric shocks, connect the array power cord to an earth grounded AC
outlet. Connection of the grounding line to a gas pipe is extremely dangerous. Never
do it.

iii
Disposing of your used NEC product
In the European Union
EU-wide legislation as implemented in each Member State requires that used electrical and
electronic products carrying the mark (left) must be disposed of separately from normal
household waste. The equipment with this mark may include electrical accessories
(e.g. memory cards). When disposing of used NEC products, you should comply with
applicable legislation or such terms which may have been agreed between NEC and
your company regarding used products. The mark on the electrical and electronic
products only applies to the current European Union Member States.
Outside the European Union
If you wish to dispose of used electrical and electronic products outside the European Union,
please contact your local authority and ask for the correct method of disposal.
Connect or remove a peripheral device from the disk array unit after turning off all
the power supplies of the disk array unit and peripherals and pulling out the power
cords from the AC outlets. If not, some units may be broken and/or you may be
electrically shocked.
To carry or reinstall the disk array unit, disconnect all cables and power cords
beforehand. If not, some units may be broken, you may be electrically shocked,
and/or a fire may occur.
Handle optical fibers carefully and gently.
The minimum bending radius of optical fiber shall be 30 mm.
Dust and/or dirt may attenuate the optical power of optical fiber causing data errors
to occur. Clean any optical fiber cable whenever it is inserted into the mating
connector with the following procedure.
1. Blow parts cleaning gas (e.g. compressed air) to the connector of the optical fiber
cable for several seconds.
2. Wipe the connector with a non-woven cloth soaked with alcohol for several passes.
3. Apply the compressed air to the connector again.
To install the unit in a rack, observe the following guidelines.
1. TMRA – If installed in a rack, consideration should be given to installing the
equipment in an environment compatible with the TMRA.
2. Reduced Air Flow – Installation in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
3. Mechanical loading – Mounting of the equipment in the rack should be such that a
hazardous condition is not created due to uneven mechanical loading.
4. Circuit Overloading – Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
5. Reliable grounding – Reliable grounding of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other than
direct connections to the branch circuit (e.g., use of power strips).
